How important are longer sway bar links with a small lift?

Put on a 2" lift(springs(IRO) & shocks(Pro Comp)) last spring. Ever since(and before), the rear end of my Jeep kicks to one side or the other going over bumps. Also replaced the rear upper control arm & ball joint at the same time, and have gone through and replace most of the front suspension as well.

Is the jumping to the side a result of not getting longer sway bar links or should I be looking elsewhere? It's got me thinking of going up to 4"'s on long arms if thats what it's going to take go solve this.

Sounds like the trackbar may be an issue, even with a 2" lift you should have an adjustable trackbar to take the lift into account.
Having longer swaybar links keeps the swaybar in the right orientation so it works properly but having the original links shouldn't give you that sort of results.

So it happened before the lift?

Sort of sounds like typical solid axle handling. Like when you go over a speed bump really slowly at an angle or take a washboard faster than 2 MPH. That's why it's called a live axle, right??

But seriously though, how much are we talking? Any other handling traits that seem odd?

Should not be a problem regarding longer rear sway bar links. Having longer links is a plus but I don't think it's necessarily the problem. My Jeep had stock links on a 2.5" lift for two years with no kicking from one side to the other.

As far as trackbar, should also not be an issue, still have stock trackbar on without any issues.

My vote is for rear lower control arms. Mine did the same thing till I replaced them

99 Cherokee-2 door,5" lift on 35" KM2s

It's done it since I've had the Jeep. Thought the stiffer/not 200,000mile springs with the lift would get rid of it.

It does it when one tire hits a bump in the road and the other doesn't.

I'll have to look into a set. Probably go aftermarket.

I don't think it's the trackbar. The lift actually centered the front axle better than it was before.
